Key result
Higher patient age (P=0.001), higher BMI (P<0.001), prone positioning, and blood loss ≥1000 mL were associated with a greater risk of developing stage 2 or higher peri-operative pressure injuries.
Why the study?
This study examined the relationship between patients' personal predisposing factors and the severity of pressure injuries developed during surgery.
Population
439 cases of peri-operative pressure injuries
Comparison
Personal predisposing and surgery-related facilitating factors
Design
Retrospective cohort study

Single associated factor may aid perioperative PI risk stratification; leaves open prospective validation of interactions.

Older age, higher BMI, prone positioning, and significant blood loss are key risk factors for developing severe peri-operative pressure injuries, highlighting the need for targeted preventative measures.
Weng et al. (2022) conducted a cohort in Peri-operative pressure injuries (n=439). Higher age, higher BMI, prone position, and blood loss ≥1000 mL vs. Lower age/BMI, supine position, and blood loss ≤100 mL was evaluated on Stage 2 pressure injuries or higher (p=<0.001). Higher patient age (P=0.001), higher BMI (P<0.001), prone positioning, and blood loss ≥1000 mL were associated with a greater risk of developing stage 2 or higher peri-operative pressure injuries.
